If you can predict what the foe will do, this move can become good. If the foe tries to use a status inflicting move, that doesn't have any power, this will stop the move working, and have the user use the move back on the original user!

A Counter for special attacks. Returns double the damage recieved, if the attack was a special attack. Because it's Psychic, Wobbuffet and this move become useless against a Dark type using special attacks.

In 1vs1, this will repeat whatever attack the foe last used, whether or not the user of Mirror Move can normally use that move, like Fearow and Recover. In 2vs2 however, it only performs the attack that last damaged the Pokémon, but always aimed at a foe, so you could attack your own Pokémon with your partner, and it'll start using that attack on you enemies.

Stops stats lowering, like a temporary Clear Body ability - for 5 turns. If you're really worried about losing Speed or Attack, then I guess you could try this, but otherwise you might want to use another attack or stat raising technique in its place. Works for both allies in 2vs2, where it would have the best effect.

The 'nighttime' recovery move. Restores 1/4HP during rain, hail or a sandstorm, Restores 1/2HP when there's no weather in effect, and 3/4HP during sunshine. Yep, no longer a full recovery as it was in Gold and Silver.

More often than not, this move is deemed useless, and the Pokémon that usually use this are ground types, Pokémon already immune to the effects of Electric attacks. A few Pokémon are able to make use of this move, but you're most likely better off just switching instead.

Works like Curse from a ghost, where the target will loose 1/4 of their total HP each turn only without the user cutting their HP when they use Nightmare, but it lasts until the target switches out or wakes up.

A very strong Fire move, only let down by the fact that this sharply reduces your Sp.Atk after use. A white herb can fix this for another use. Usually used when a Fire types is primarily a physical battler, and needs a fire type for backup.
